Now, operator, from the position operation transmitter 9 away from wire tensioning device 1, can carry out the volume of the first chain 6 accordinglyAround operation. Therefore,, even if hypothesis stringing 960 and first is grabbed grasping of line device 900 and come off, also grab line device without worry because of first900 directions to operator fly here and meet accident or get an electric shock because contacting stringing 960.

The length of wishing if the first chain 6 is only reeled to the inside of turnbuckle main part 2, operates transmission by operatorMachine 9, is sent to receiver 10 from transmitter 9 wirelessly by the stop signal of motor. If electric rotary machine 7 is receivedFrom the stop signal of receiver 10, motor stops, and the first being rotated in the forward of rotating shaft 30 of rotary drive mechanism 3 stops.

Next, in step S5, judge whether setting up of stringing 960 be abundant, be judged as setting up fully of stringing 960Situation under, in step S6, the operator on electric pole C is connected stringing 960 with electric pole C.

On the other hand, in step S5, be judged as in the inadequate situation of setting up of stringing 960, utilizing and be installed on theSecond of three installation portions 12 are grabbed line device 920 and grasp the free end 960a side of the stringing 960 that sets up and remain on electric pole C side.

Next, grab line device 900 from first and unload stringing 960, carry out abovementioned steps S3.

Next, grabbed after line device 900 grasps by first in the free end 960a of stringing 960 side, grab line device 920 from secondUnload stringing 960, carry out abovementioned steps S4.

In step S5, again judge whether setting up of stringing 960 be abundant. Suppose at the frame that is again judged as stringing 960If in inadequate situation, only repeating step S3 and step S4 on demand.

In addition, in the case of the electric power storage of battery 11 exhausts, replace electronic revolving with the ratchet handle 140 shown in Figure 17Favourable turn 7, manually gives rotary driving force to rotary drive mechanism 3. (A) figure of Figure 17 is the front view of ratchet handle 140, (B)Figure is top view.
